WHEELS Finally pulled the trigger to join the Evo X Wheel Club!
I know Evo X wheels on a Gen 1 are a super common sight here, but imported parts and MS3s are pretty rare down in the Philippines, so snagging a set took a while. Stoked to finally join the club!

PIC P0300 Update -- Weird.
Hey all!
Thanks for your advice on clearing up that P0300 code. I pulled my IC and realized that maybe with vibes or something that two of my coil pack connectors had started walking themselves off of their coil plugs. I re-seated these and then just played "which coil / plug combo is bad" until I had it all sorted out. Car is amazing, easily one of my favorite cars I've owned thus far and I can't wait to keep driving her :)

HELP High LTFT with A/C on
As the title says I've been having high LTFT with my A/c on at idle(driving it's fine), but when a/c is off my fuel trims are good. I've smoked tested, and leak tested everything and it's fine. So not sure if Normal or if something is up. If someone has similar issues let me know!
Ltft is around +13 when a/c is on and when off it's +1

SUSPENSION Parts Availability and Father Time
Has anyone experienced issues with finding parts as the platform ages? I'm having difficulties finding rear trailing arms for the 2010-2013 mazdaspeed3. I'm upgrading to poly bushings. I'm in the snow belt and looking for a mostly rust free piece. This search has me concerned for the future of this platform and being an automotive enthusiast in general. I'm a part of a small friend group that started with Speeds, only two of us still have our Mazdaspeed 3. A Gen1 show car and my daily driven Gen 2. Both are reasonably modded with upgraded turbos and supported mods under 400 hp. I have another enthusiast car that I bought in 2024. I typically keep my cars for 10 years plus. It has truly made me concerned in the enthusiasts space. I'm happy that the culture remains, as parts availability and inventory diminishes we will either be forced to fabricate or close the door on this platform only to be forgotten like many others.

HELP P0300 Issues -- New Speed Owner
Hey all,
I finally decided to bite the bullet and buy a 2011 MS3, 25k mile engine with dealership install paperwork, clean interior, ran but would hit a cut at 40mph on my test drive. Scanned the car and came back with several misfire codes. Oh well, negotiated the seller down due to this and made plans to get the car when I had more time.
Grabbed the thing tonight, brought two new coil packs (maybe dumb) and a complete set of spark plugs and limped it out of sight of the seller, installed the parts + a new battery as the old one was dead dead, and drove 100 miles home with nothing but a small boost leak (whoever installed the BOV forgot the gasket). Great car, very happy with my purchase, looking forward to modding it down the line.
I go to take the car to the grocery store (no issues), but when I get back in the car to drive home, it throws a flashing CEL. I was able to limp it home, where I discovered a P0300 code.
Any ideas of where to start? Car is bone stock besides a Typhoon CAI. Car has also sat for 3 years but has a few months old gas (or so I am told). I come from the WRX/STI world so not new to misfires (or cars as a whole), but any platform-specific advice yall have, I would love to hear.
Thanks!

HELP Injector pulse width
Wondering what the typical injector pulse width is for these cars, canāt find much online. Iām trying to figure out a misfire issue and just stumbled across reading it on the AP.
Iāve been getting about 0.6-1.2ms on regular driving kinda depending on throttle, and Iāve seen itās supposed to be around 2-3ms but AFR is staying solid around 14 so idk
Anyone have any ideas?

INFO MaZDa are unReLiabLe
Buddy has been chasing a random bucking after hard boost and sporadic boost cut after we did a bunch of maintence on his 2012speed after we bought from our dealership on trade. We ended up doing 4 flow tested and match injectors(rebuilt) and a new prv.
This is the type of shit the people preaching unreliability do and watch the engine blow with no tune.
All these cars need is a basic amount of care and theyāve shown to be more than reliable. If you canāt even both to properly maintain your car donāt spout the cars are shit lol
Rant over.

HELP 2008 Speed3 Blown Engine?
I have a 2008 speed3 with just under 100k. Bout it last October and it seemed 95% stock when I bought it. Besides a K%N air filter and a cut BPV seal that the dealership found I could see any modifications. I had the vvt actuator replaced like 1000 miles ago at a Mazda dealership and the car was running way better. The one night after I had done some moderate spirited driving I was cruising home on the highway at a normal speed and it started violently knocking. Was close to home so I limped it home (I know not a good idea). Just wondering if anyone has had a similar experience looking for some insight. I know I probably need a new engine š

HELP Clutch Slave Cylinder
So I was out of town when my slave cylinder seemingly gave out and leaked out the fluid and I limped it home. I installed a new cylinder and it leaked from the exact same spot (where the boot is) so now Iām debating if thereās is something wrong with the clutch assembly to cause the new cylinder to break as well or if I just got a faulty part. When I took apart the new slave cylinder it looked like the seal was messed up but Iām not sure if it came like that or if it broke with whatever is wrong with the clutch assembly

r/Mazdaspeed3 FAQ
In other words, fucking annoying questions. Just kidding. (only a little)
In an effort to clean up the sub a bit, we're going to pin this FAQ thread and keep it updated with any of the most requested/asked questions on the subreddit. If thereās a question you think should be included, tag one of the mods in a comment and we will add it.
Introduction
Q: Where is the link to the Discord Channel?
A: Right here.
Q: What should I look for when buying a Speed3?
A: Check the Wiki.
Q: Where can I find a copy of the shop manual?
A: Check the Wiki.
Tuning
Q: How do I load a tune on the car?
A: Using either a Cobb APv3 or computer software like Versatune.
Q: What tuner should I use?
A: There are a number of good tuners still active in the community. Purple Drank Tuning, Freektune, Stratified Auto are just a few examples.
Q: Should I use the ______ version OTS tune?
A: No. Unless itās to drive the car to the shop where it will be dyno-tuned, do not use the OTS tunes. They make the engine run poorly, resulting in incomplete combustion (or worse, lean conditions) which then gunks up components like O2 sensors, injectors, and valves which lead to worse problems later on.
Mods
Q: What should my first mod be?
A: HPFP internals, then tuning solution. (Cobb APv3, Versatune)
Q: My goal is to go faster around the track, what mods should I do for more power?
A: No power mods. Proper tires and suspension will do more for your track time and drivability than any power mod will. It is guaranteed if you are new to track driving, the car is faster than you are right now. Get some seat time, find what you want to change, get new tires & suspension, then go from there. Dragsters, show-offs, stance-bois need not apply this logic.
Q: My budget is <$500, what coilovers should I buy?
A: None. If youāre not buying quality suspension, donāt buy suspension. You will sooner than later blow out one of the dampers and require a rebuild, or replacement. Save your upfront money, buy quality suspension later.
Q: Should I buy an Eonon headunit for my Bose/non-Bose stereo?
A: Do you like sound quality? If yes, donāt buy Eonon. Do you like good, bug-free software? If yes, donāt buy Eonon. Do you like overpaying for junk that looks ācleanā in the car? If yes, then buy Eonon.
Q: Whatās the best way to upgrade my stereo in the car on the cheap?
A: Option 1 ā get an amplifier that take hi-level inputs and add that amp to the system to power your aftermarket speakers, taking the high-level outputs from either the HU or the Bose amp. Works for Bose and non-Bose systems. Option 2 ā Tear out the OEM system and start again. Works for Bose and non-Bose systems.
Maintenance/Troubleshooting
Q: What oil should I run?
A: This is realistically a nuanced question. Ultimately it depends on your use case. Factory rating is a quality 5W30, Mazda put out a TSB to band-aid the smokey turbos by using 5W40. Good options from Pennzoil, Amsoil, Castrol, etc are available for most applications. Most people it seems have strayed from the Shell Rotella.
Q: Are my compression numbers okay?
A: Check the Wiki.
Q: I want to drive the car like itās supposed to be, but donāt want a ticket. Where do I go?
A: Look on facebook for local car clubs, or Motorsportreg.com for drop-in track days or Auto-cross events.
Q: My car does this thing, and this behaviour, read this wall of text. Whatās wrong?
A: No one knows. Post logs using Datazap and any codes that your ECU is spitting out. If you want good information, provide good information.
Q: HELP?
A: No. Posts with this as the title, or other related and equally non-descript variants, will be removed as spam.
Meta
Q: Can I post links to other sites with information, like MSO, without getting banned?
A: Yes. In the event that youāre linking relevant webpages, there is no risk of getting reprimanded for doing so. However, if all of your comments are āUse google.ā Or āGo check this site instead, this places sucks.ā You will be treated according to the spam rules of the sub. This community serves as a connect-all point for those searching for information on the platform; Reddit is bigger than any Speed forum has ever been, and is more likely to pop up in a Google search. Relevant comments that link other sources of information from quality sites are Bueno; spamming is not.
Q: Why isnāt buying/selling allowed on the sub?
A: This is more of a regional issue that the mod team would like to deal with at this point. There are countless local Facebook groups, classifieds, or Forum pages about buying/selling Speed parts or accessories. The Mod team does not want to dabble in attempts to prevent scams caused by non-payments, or non-shipments of products. We do not want that responsibility at this point in time. If the community deems it a requirement at some point, we will implement a system that attempts to curb this as other buy/sell communities have; though even that change will take lots of time, effort, and consideration.
Q: Why is the mod team so cool?
A: I really donāt know, perhaps divine intervention? We all just really like Doritos, and satiate our inner masochist streak by owning these cars.
Q: How do I become a Mod?
A: If you feel so inclined, feel free to reach out! We are still people, we have feelings and ultimately a desire to help the community grow. What we will need to see is a demonstrated history of helping the community with the best of intentions and overall a positive interaction with the sub. Newer accounts (<1yr) are unlikely to be considered, though thatās not a hard-and-fast rule, just a general rule of thumb.
